Node red with termux - error permission denied cannot open port /dev/bus/usb/001/006

[Asadsaeed003091]

Hy! I am using node-red mobile via a termux, I am trying to connect a RFD 868 module to mobile and receive serial data through it via a USBA port. I have connected a USB type C docking station with mobile which have three USB A port. When I connect the docking station it shows three ports and I have granted access to the ports too via termux api. But when I try to use the port on Nod-red I receive the following message "error permission denied cannot open port /dev/bus/usb/001/006". Through same setup on the same port via "free USB serial" app I can receive serial data successfully. But on node-red mobile app its not working
